[Htmlunit-user] removing a tbody leaves tablerows inside accessible through id
|

While unittesting some advanced dynamic table code, I
mentioned some weird things going on. It took me a
while to pinpoint the situation, but I've got it. It
appeared to be reproducable using a very simple table
which I grabbed from the HTMLUnit homepage.
The problem is that after removing a tbody from a table
using removeChild, the rows inside are still accessable
throug document.getElementById(rowId), which
unfortunately isn't acceptable. This code passes in
'any' browser, but throws a TypeError in my Unittest
using HTMLUnit.
The code I used to simply reproduce the strange behaviour:
<html>
<head>
<title>Table sample</title>
</head>
<body>
<table id="table1">
<caption>My complex table</caption>
<thead>
<tr>
<th>Number</th>
<th>Description</th>
</tr>
</thead>
<tfoot>
<tr>
<td>7</td>
<td></td>
</tr>
</tfoot>
<tbody id="body1">
<tr id="row1">
<td>5</td>
<td>Bicycle</td>
</tr>
</tbody>>
<tbody id="body2">
<tr id="row2">
<td>2</td>
<td>Tricycle</td>
</tr>
</tbody>>
</table>
<script type="text/javascript" language="JavaScript">
var table = document.getElementById('table1');
table.removeChild(document.getElementById('body1'));
table.removeChild(document.getElementById('body2'));
if (document.getElementById('row1') != null) {
throw new TypeError('row should be null by now!!');
}
</script>
</body>
</html>
